Feat: Added Game start sound , Check sound and Game over (checkmate) sound similar to Chess.com

[Moh1tsingh]

Problem : There is only sound for every move made but not for other things like check , checkmate and game start

(The sound in the recordings is somehow noised due to some OBS bug , but in real all the sounds are exactly same as Chess.com )
